Currently within Command there is not a way to transfer an Opportunity between pipelines, teams, nor Market Centers. If an Opportunity is created in the Listing pipeline it cannot be moved to the Buyers pipeline and vice versa. Similarly, if an Opportunity was created on a Team pipeline, it cannot be moved to the Personal pipeline nor to another team, and Personal Opportunities cannot be moved to a Team.
If an Opportunity was accidentally created for the incorrect Pipeline or Market Center, the Opportunity will need to be archived and then recreated with the correct Pipeline type and Market Center.
Please see the following for more information:
Change the Account a Lead/Contact Is Worked In (Team or Personal) (Teams)
Mark an Opportunity as Lost or Archive an Opportunity
